VCC – VEE(2) Supply voltage –0.5 10.5 V
VCC –0.5 7
VEE 0.5 –7

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltages referenced to GND unless otherwise specified.
(3) The package thermal impedance is calculated in accordance with JESD 51-7.

6.2 ESD Ratings

VALUE UNIT
V(ESD) Electrostatic discharge Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all pins(1) ±2000 V
Charged device model (CDM), per JEDEC specification JESD22-C101, all pins(2) ±500
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.

VIL Low-level input voltage VCC = 2 V 0.5 V

VIS Analog switch I/O voltage VEE VCC V
tt Input transition (rise and fall) time VCC = 2 V 0 1000 ns
VCC = 4.5 V 0 500
VCC = 6 V 0 400
TA Operating free-air temperature –55 125 °C
Cpd Power dissipation capacitance(3) 50 pF
(1) All unused inputs of the device must be held at VCC or GND to ensure proper device operation. Refer to the TI application report, Implications of Slow or Floating CMOS Inputs, SCBA004.
(2) In certain applications, the external load resistor current may include both VCC and signal-line components. To avoid drawing VCC current when switch current flows into the transmission gate inputs, the voltage drop across the bidirectional switch must not exceed 0.6 V (calculated from ron values shown in Electrical Characteristics table). No VCC current flows through RL if the switch current flows into the COM OUT/IN A terminal.
(3) Cpd is used to determine the dynamic power consumption, per package.
PD = Cpd VCC2 fI + Σ (CL + CS) VCC2 fO
fO = output frequency
fI = input frequency
CL = output load capacitance
CS = switch capacitance
VCC = supply voltage
